Kylie Jenner is officially trying to get her hands on just about everything under the sun … filing docs to take over the hair industry.

Jenner has applied for a trademark for “Kylie Hair” — a line to include hair care products — shampoos, conditioners, oils, gels, mousse and dye. Kylie’s plans don’t just stop at what to put in your hair, she’s also trying to lock down products to style it too … dryers, curling irons and brushes.

Kylie’s older sister, Kendall, also recently filed docs to trademark bags, clothing and hair accessories under her own name.

Kylie Cosmetics is already a giant brand — it’s made her a billionaire — and Kylie Skin is set to be a massive success as well.

TMZ broke the story, Kylie filed to trademark “Kylie Baby” earlier this week … a line to include strollers, cribs, bouncers, bottles and a whole lot more.
